<p><P>PROBLEM TO BE SOLVED: To provide a duct for a ship and the ship with the duct for the ship for arranging the duct for the ship, capable of suppressing manufacturing cost, and capable of preventing the generation of vibration, while maintaining performance as an energy-saving device. <P>SOLUTION: This ship 1 with the dust for the ship has a hull 2, a propeller 3 and the dust 6 for the ship arranged in a stern of the hull 2. The duct 6 for the ship is composed of a cylindrical duct 4 and a pair of stays 5 connecting the cylindrical duct 4 and the hull 2. The pair of stays 5 are symmetrically arranged on both boards of the hull 2 at an elevation angleαs and an inclinationθs with respect to a horizontal plane 1c. Central surface 5c of the pair of stays 5 are inclined only by an opening angleθs with respect to the horizontal plane 1c, and an intersection Q with a plane including the stern side edge of the cylindrical duct 4 is separated only by a deviation distance Hs from a propeller shaft 3c. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
